Man, through the ages, has undergone many changes from the time when he depicted a herd of mammoths on the walls of his cave to these days when he can create beautiful pictures and even make coffee by use of computer technologies without leaving his favorite chair. The 20th century made huge steps in developing computer technologies and reached many goals that made our life much easier. What should we expect in the 21st century?
First of all, I think that the pace of our life will speed up: we will move faster from one place to another, from one continent to another using high speed jet airplanes. Second of all, I believe that we will be able to do many things that take much time now without leaving our house. Computers will be everywhere including out clothes. Many people will have chips and mini computers inserted in their heads to hold huge amount of information and have a quick access to it.

But what will be the most amazing thing in the 21st century is the flights to the outer space and Mars that will be available to all people. Scientists say that Mars has many things similar to the Earth's. Moreover, they say that with the help of modern technology people can artificially create conditions that will allow people to live there on the constant basis.
To sum up, I am sure that many amazing changes will be brought by the 21st century.
Furthermore, I think that with the help of the contemporary technologies people can do many things that were even difficult to imagine a century ago. So, nowadays it is rather difficult and even impossible to imagine all changes that will happen in the next decades.

119. It has been more than 30 years since man first landed on the moon. Some people think that space research is a waste of money. Discuss.
For over fifty years, a number of nations have been involved in the exploration of outer space. This research has been very costly, of course. Has this money been well-spent or wasted?
Some people believe that all or most space research should be eliminated because of its incredible expense, not only in terms of money, but also in terms of scientific and human resources. These people point out the fact that it cost billions of dollars to send astronauts to the moon, but all they brought back were some worthless rocks. These people say that the money and effort now being wasted in outer space could be spent for homeless people, improving the education system, saving the environment, and finding cures for diseases.
However, other people believe that space research has provided many benefits to mankind. They point out that hundreds of useful products, from personal computers to heart pacemakers to freeze-dried foods, are the direct or indirect results of space research. They say that weather and communication satellites, which are also products of space programs, have benefited people all over the globe. In addition to these practical benefits, supporters of the space program point to the scientific knowledge that has been acquired about the sun, the moon, the planets and even our own earth as a result of space research.
I agree with those people who support space research and want it to continue. Space research, as shown, has already brought many benefits to humanity. Perhaps it will bring even more benefits in the future, ones that we can not even imagine now. Moreover, just as individual people need challenges to make their lives more interesting, I believe the human race itself needs a challenge, and I think that the peaceful exploration of outer space provides just such a challenge.
